long-term memory
The vast and virtually limitless store of knowledge and prior events.
executive function
The aspect of the brain that supervises the memory process by regulating the flow of information and controlling key processes.
metacognition
The process of knowing about knowing.
general intelligence (g)
A construct thought to underlie one’s ability to adapt and determine one’s competence level.
intelligence quotient (IQ)
A score calculated from results on an intelligence test originally derived from the formula of (mental age/chronological age) × 100, resulting in an average score of 100.
intellectual disability
A disorder characterized by significantly below-average intellectual functioning (an IQ of 70 or lower) and impaired adaptive functioning, with onset prior to 18 years of age.
gifted
Significantly above-average intellectual functioning as indicated by an IQ of 130 or higher.
